“…Cryptosporidium spp., Ascaris spp., and Baylisascaris spp. had the highest prevalence in our study, similar to findings in wild Andean bears in Peru (Figueroa 2015) and Colombia (Zárate-Rodriguez et al 2022). We report for the first time Trichomonas spp., Coccidia, and Microsporidia in wild Andean bears.…”

“…is a protozoan whose definitive hosts can be herbivores such as cattle, and carnivores such as canids or felids (Feng et al 2011). It has been reported in both wild and captive polar bear species (Ursus maritimus), sun bear (Helarctos malayanus), black bear (U. americanus), brown bear (U. arctos), and Andean bear (Duncan et al 1999, Rademacher et al 1999, Figueroa 2015, Zárate-Rodriguez et al 2022. The main sources of transmission are from consuming water contaminated with parasite oocysts, interaction with infected domestic animals, and the presence of human settlements with poor hygienic conditions (Arias-Bernal and Yarto-Jaramillo 2019, Xiao et al 2000).…”

“…Information about parasite presence and occurrence and their effects on Andean bear population dynamics and welfare (Figueroa 2015, Mata et al 2016, have been reported mostly from captive individuals (Vela-Vargas et al 2021b), with few studies in free-ranging Andean bears as reported in Peru and Ecuador (Figueroa 2015, Guerrero andCastellanos 2016). In Colombia, only Toxoplasma gondii has been registered in captive individuals (Arias-Bernal and Yarto-Jaramillo 2019); and studies performed in the western range in wild individuals registered Eimeria spp., Ascaris spp., and Ancylostoma spp., among others (Zárate- Rodriguez et al 2022).…”

The Andean bear (Tremarctos ornatus) is the only species of the Ursidae that inhabits the Andes in South America. The natural history of the species and health issues related to infectious diseases, particularly the presence of gastrointestinal parasites (GIP), is unknown. To determine the prevalence, infestation, and richness of GIP in fecal samples of wild Andean bears, 21 fecal samples were collected at different sites of the Chingaza National Park, Colombia, and its buffer area from February to April of 2019. Samples were analyzed by qualitative and quantitative coprological techniques. A minimum of one parasitic species was present in 100% (n = 21) of the samples and in 86% of them, co-infection was detected. In decreasing order, the observed parasite prevalence was as follows: 100% for Cryptosporidium spp.; 62% for Ascaris spp.; 38% for Baylisascaris spp.; 33% for Trichomonas spp.; 19% for Strongylus spp.; 14% for Microsporidia and Coccidian oocysts; followed by Trichostrongylus spp. and ciliated protozoans with 10%; and Ancylostoma spp., Blastocystis spp., and Fasciola spp. were present in 5% of the samples. The presence of Blastocystis spp., Baylisascaris spp., Ascaris spp., and Cryptosporidium spp. suggests a possible rotation of parasitic species between domestic and wild host species. This is the first report of GIP for Andean bears in the east range of Colombia, which could help to generate other studies in the country and South America.

Parasites in Bears (Ursidae): Sampling Gaps in the Spectacle Bear (Tremarctos ornatus)

Parasites are part of the natural processes that help regulate populations and maintain ecosystems balanced. There is a growing recognition of parasites as important factors in the conservation of species, mainly those vulnerable to extinction in a changing environment. Bears are good biological models for monitoring infectious agents in wildlife, given their life cycle, broad home range, and severity of interactions with humans and their domestic animals as a result of their behavioral plasticity, intelligence, and omnivorous food habits. In the Andean region, the only bear species listed as vulnerable is the Tremarctos ornatus. To determine the sampling gap and prioritize the approach for understanding parasite diversity in bears, I performed a systematic review and metanalysis of the documented parasites of bears across the world and discussed the possibility of the parasites recorded in these other species being present in the T. ornatus in the Andean region, specifically Colombia. In 283 relevant references, 647 records were found of 189 parasites in 37 countries. Of the bears with parasites recorded, Ursus americanus had the most numerous and complete records. The tropical species H. malayanus, M. ursinus, and T. ornatus showed the smallest parasite diversity and unseen species estimate, despite being the region where the greatest diversity of parasites was expected. Of interest are around 80 parasites that have been recorded in seven non-Colombian bear species but are documented in other species in this country.
